Duty Cycle And Overheating
Duty Cycle is percentage of 10
minutes that unit can weld at rated
load without overheating.
If unit overheats, output stops, and
cooling fan runs. Wait fifteen
minutes for unit to cool. Reduce
amperage or duty cycle before
welding.
NOTICE Exceeding duty cycle
can damage unit and void warranty.

Notes
Duty cycle is the percentage of
10 minutes that unit can weld at
rated load without overheating.
If unit overheats or duty cycle is
exceeded, the output stops, a
Help message is displayed, and
cooling fans run. Wait fifteen mi-
nutes for unit to cool. Reduce
amperage or duty cycle before
welding.
NOTICE –
Exceeding duty cycle
can
damage
unit
and
void
warranty.
